2 Claims.

The invention relates to a new and useful improvement in a dispensingcontainer for powdered materials. It is a common practice to attach aclosure end having a perforated nozzle to the body portion of a metalcontainer by an outside skirt which makes frictional contact with theupper end of the body portion. When the can body is of generalrectangular shape with rounded corners, the flat sides of the body walloften spring inwardly away from the depending skirt of the closure endwith a resulting leakage of powder.

This is particularly true in containers of relatively large capacity,where the fiat side walls are of considerable width.

An object of the present invention is to provide a container of theabove type with a reinforcing member which is attached to the closureend as a unit and which carries an upwardly extending member adapted toengage the inner upper edge portion of the body wall so as to prevent itfrom springing inwardly away from the depending skirt.

A further object of the invention is to provide a container of the abovetype with a fiber gasket disposed within the skirtedportion of theclosure end so as to be contacted by the upper edge of the body wallwhich gasket is clamped to the closure end by the reinforcing member.

In the drawings:

Figure 1 is a top plan View of a powder dispensing container embodyingthe improvements;

Figure 2 is a sectional view on the line 2-2 of Figure 1;

Figure 3 is an enlarged section of a portion of the upper end of thebody wall, the lower portion of the closure end, the reinforcing ringand the fiber gasket, and showing the arrangement of the parts when theclosure end is attached to the body; and

Figure 4 is a plan view of a portion of the reinforcing ring.

The improved powder dispensing container includes a body having flatsides and rounded corners. It also includes a perforated closure endformed with a nozzle section and a skirted section which are joined byan interfolded seam. The skirt of the skirted section is shaped so as tohave flat portions and rounded corners conforming to the shape of thebody of the container and this skirt portion makes frictional contactwith the outer upper portion of the body wall. Within the skirtedportion of the closure end is a reinforcing metal member provided with aretaining part extending into the interfolded seam. This reinforcingmember also has a depending portion and an upwardly extending portionwhich upwardly extending portion is so shaped and dimensioned as toengage the inner end of the body wall all along the flat sides thereofand thus prevent the body wall from springing away from the dependingskirt. Within the skirted portion of the closure end is a fiber gasketwhich extends over the end of the body Wall so that the body wall willmake tight sealing engagement with the gasket. This gasket is retainedas a unit with the closure end. Attached to the nozzle section is a capwhich. may be rotated to bring the perforations therein into alignmentwith the perforations in the upper closed end of the nozzle when it isdesired to dispense powder.

Referring more in detail to the drawings, the dispensing containerincludes a body portion I which is of metal. Said body portion is beadedat 2 at a short distance beneath the upper end thereof.

There is a closure member which includes a nozzle section 3 and askirted section 4. The nozzle section is provided with a closed end 5having perforations E therein through which the powder may be dispensed.The skirted section 4 is joined to the nozzle by an interfolded seam 1.This skirted portion has a depending skirt 8 provided with flat sidesand rounded corners conforming to the fiat sides and rounded corners ofthe body of the container. This depending skirt is dimensioned so thatit makes frictional contact with the outer face of the body wall abovethe bead therein.

A reinforcing member 9 formed of metal is adapted to be secured to theinterfolded seam. As shown, the reinforcing member has a retaining partIll which extends into the interfolded seam so this retaining part isgripped and thus the reinforcing member is secured to the closure end asa unit. Thisretaining portion of the reinforcing member is circular inshape to conform to the shape of the seam joining the skirted section tothe nozzle section. This reinforcing member has a depending wall IIwhich carries an upwardly extending wall l2. These: walls II and I2 areshaped so as to conform with the flat sides of the container body. Italso has rounded corners indicated at iii in Figure 4. This upstandingmember I2 of the reinforcing member is curved outwardly and isdimensioned and positioned so as to engage the inner upper end portionof the body wall a short distance from the end and this is what preventsthe body wall from springing inwardly away from the skirt. Furthermore,the body wall is curved inwardly at its upper end and extends over theend of the member I2 when the closure member has been applied to thecontainer body. This aids in holding the closure member on.

A fiber gasket [4 is placed inside of the skirted section of the closureend. This gasket, extends over the end of the upwardly projecting partl2 of the reinforcing member and also extends over a,

portion of the reinforcing member adjacent the retaining part isthereof. The gasket is placed in the skirted part, then the reinforcingmember is inserted and the interfolded seam is then formed so as tosecure together the reinforcing member, the closure end and gasket as aunit. The upper end of the body wall may be bent. in-. wardly asindicated at I5 so as to provide a reinforcement for the upper end ofthe body wall where it contacts with the gasket so as to aid in the:forming of a tight. seal, preventing any escape of powder.

Attached to the, nozzle section is a. cap I25. This cap it is providedwith perforations H. The depending skirt of the cap has a beadedconnection 8 at its lowerend with the nozzle which holds the cap placeon the nozzle and at the same time permits it to be rotated thereon.There are the usual stops for limiting the rotation of the cap so as tobring the perforations H in the cap into proper alignment with theperforations 6 in the, closed end 5 of the nozzle section.

It is obvious that minorchanges in the details of construction may bemade without departing from the spirit of the invention as set forth inthe appended claims.
